Unable to access the OMV Web interface after changing port to 8080

I've been using OMV for the past few months without any kind of error I couldn't solve myself, but I seem to have broken something and can't fix it!
my problem is that I am after assigning port 8080 to the web interface and can no longer access it.

I believe that I am unable to access it because of a previous docker container I had installed that used the port 8080 and has kept the configuration, stopping me from accessing the interface.

Does anyone know how to change the port without accessing the web interface?
